HENRY G. ZSCI-IOERNER, OF

COOLING SYSTEM FOR,

Application filed June 9,

To all whom it may concern.

Be it known that I, HENRY G. Zsononn- NER, a citizen of the United States, residing at Frankenmuth, in the county of Saginaw and State of Michigan, have invented certain new and useful Improvements in Cooling Systems for Combustion Engines, of which the following is a specification.

In carrying out the present invention, it is my purpose to provide a cooling system for internal combustion engines, that employs both air and water as the cooling me dium, the primary object of the invention residing in the provision of such a system, wherein the water carrying means for the different cylinders of the engines may be removed at will, for the purpose of repair or renewal.

A further object of the invention, is the provision of a water system wherein the structural elements included in the system are extremely simple of construction, and may be manufactured and installed at minimum cost.

A still further object of the invention is to provide as a component part of this cooling system, a highly novel and simplified form of radiator, wherein the water passing therethrough may be more effectively cooled than in the present types of radiators with which I am familiar.

The nature and advantages of the invention will be better understood when the following detailed description is read in connection with the accompanying drawings, the invention residing in the construction, combination, and arrangement of parts as claimed.

In the drawings forming part of this application, like numerals of reference indicate similar parts in the several views, and wherein Figure l is a side elevation of an internal combustion engine, equipped with my novel cooling means.

Figure 2 is an enlarged detail cross section of one of the removable water carrying elements that is adapted for positioning over one of the cylinders of the engine.

Figure 3 is a transverse cross section thereof.

Referring to the drawings in detail, and particularly to Figure 1, there is shown an internal combustion engine, comprising four vertically disposed and spaced cylinders, and the usual crankcase 6.

My improved system constitutes the provision of cylindrical water carrying elements 7, that are adapted for positioning over said cylinders, and to totally surround the same, as clearly shown in this figure. As more clearly shown in Fig. 2, each of these water carrying elements embodies an upper and lower hollow ring 8 and 9, respectively, which are preferably rectangular-shape in cross section, and are integrally joined to gether, and have communication with each other, through the medium of a circular row of pipes or tubes 10. Formed integral with the upper ring 8, and in communication therewith is a hollow cap 11. The hollow caps 11 of each of the water carrying elements 7 are in communication through branch pipes 12 of a main water pipe 13, that is inclined upwardly towards its forward end, and has communication with the upper end of a novel form of radiator 14:.

The radiator 14 includes the usual headers at the top and bottom thereof as indicated at 15, which are connected by the plurality of spaced vertically disposed water tubes 15, that are in communication with the headers to permit a circulation of water through the radiators from one header to the other, the usual fan 18 carried by the motor and operated with the crank case being positioned immediately in the rear of the radiator for circulating air through the same for cooling the water or other cooling medium in the pipes 16, and for also directing a current of air against the cylindrical water carrying element 7 for additionally cooling the water in the system and in said element.

The lowermost ring 9 of each of the water carrying element-s 7 that surround the cylinders are in communication with branch pipes 19 of a common manifold 20, this manifold communicating at 21 with a desirable form of water pump 22, that is in communication through the medium of a pipe 23 with the radiator 14.

It will be obvious that I have provided a highly novel cooling system for combustion engines, and one that will answer all of the purposes above ascribed, and even though I have 11 arein set forth the most practical embodiment of the invention, it is nevertheless to be understood that minor changes may be made the-rein, without departing from the spirit and scope of the invention as claimed.

Having thus described my invention, what I claim as new, and desire to secure by Letters-Patent, is:

In combination with an engine cylinder and a fan arranged to direct a blast of air upon the cylinder, a cooling system comprising columns arranged at the opposite side of the fan from the cylinder and spaced from each other the fan being adapted to' draw blasts of air between the columns, spaced pipes arranged about the cylinder andidisposed in the path of the blast from HENRY e; zeononnt nn
